WPC Qi v1.2 15W Compliant Wireless Power Receiver Controller IC

Overview

TopologyWireless Power Transfer
Input voltage18 V
Output 17.5 V / 2 A
IC revision1.4

Description

The TC7766WBG is a 15W wireless power receiver (RX) IC compliant to the Qi v1.2 standard of the Wireless Power Consortium (WPC). The TC7766WBG includes a rectifier circuit, a digital control circuit, a modulation circuit, a demodulation circuit and a regulator circuit which controls the supply voltage to the load. The IC includes all functions needed to construct a standalone wireless power RX system. In addition, it enables a host controller to check the wireless power system status by accessing its registers via I2 C. TC7766WBG allows designes with a minimum amount of external components. e.g. uses an internal oscillator and generates its own power supply voltages with an built-in LDO.
